Abstract 9170: Medication Reconciliation: Much Remains to Be Done

Introduction: Medication reconciliation had been a persistently national patient safety issue. Despite several efforts, the rate of error is still significantly high, and the measures that had been taken to improve this process are lacking data to prove their efficacy in reducing medication errors. In this retrospective study, we will measure the efficacy of medication grouping intervention on the discharge platform ion order to reduce medication error. The intervention was grouping medication according to pharmaceutical class, in addition, bundling home and inpatient medication. Methods: This retrospective study was conducted in a single-center teaching hospital. A multidisciplinary team changed the discharge medication platform. This intervention was done in July 2019. Afterwards a total of 1395 patients were screened. The control group were 760 patients, versus 635 patients in the intervention group. Patients who were not admitted under the medical team service were excluded, and patients who had less than 7 medications on admission were also excluded. After screening, the remaining patients were subjected to detailed charting for medication error, which was done in 179 subjects in the control group vs 176 intervention groups. The primary outcome was medication error on discharge, which was measured by 2 different independent physicians. Furthermore, a subgroup analysis was done comparing residents' vs hospitalists' medication reconciliation errors on discharge. Results: A total of 329 patients were studied. In the control group, the percentage of errors noted was 42/161 (26.08%), while in the intervention group errors were noted in 37/168 patients screened (22.02%) a significant reduction of 4.06% in the percentage of errors noted. Conclusion: The electronic intervention of grouping medication by pharmaceutical class and bundling home and inpatient medication resulted in a reduction of medication error upon discharge medication reconciliation.
